Answer:

is mine correct? please tell

Answer 2

Step-by-step explanation:

taking (1/x) = a

&. (1/y) = b

2/x + 3/y = 2

2a + 3b = 2

2a + 3b - 2 = 0 (eqn no. 1)

5/x + 10/y = 5⅚

5a + 10b = 35/6

30a + 60b = 35

30a + 60b - 35 = 0 (eqn no. 2)

(equal the value of a or b in both the eqn)

multiplying eqn no. 1 by 15

15(2a + 3b - 2)

30a + 45b - 30 (eqn no. 3)

(now vale of a is same in both the eqns)

(subtracting eqn no. 2 by eqn no. 3)

(30a + 60b - 35) - (30a + 45b - 30) = 0

30a + 60b - 35 - 30a - 45b + 30 = 0

(30a - 30a) + (60b - 45b) + (-35 + 30) = 0

15b - 5 = 0

15b = 5

b = 5/15

b = 1/3

(putting the value of b in eqn no. 1)

2a + 3b - 2 = 0

2a + 3(1/3) - 2 = 0

2a + 1 - 2 = 0

2a - 1 = 0

2a = 1

a = 1/2

a = 1/2

1/x = 1/2 [a = 1/x]

x = 2

b = 1/3

1/y = 1/3 [b = 1/y]

y = 3
